Abstract (en)
[origin: WO2015128390A1] A method for determining equalization filter parameters for a headphone, the method includes determining a composite response curve based on an average of amplitude response values measured from a plurality of measurement locations, the plurality of measurement locations, in cumulative, substantially spanning at least the headphone transducer, and determining the equalization filter parameters based on the determined composite response curve.
